Deep Groove Ball Bearings SKF 6222 -2Z

The SKF 6222-2Z deep groove ball bearing, with a 110 mm bore and sheet metal shields on both sides, provides protection against dirt particles in industrial applications.

As a single-row radial ball bearing, the 6222 -2Z deep groove ball bearing is designed for heavy-duty shaft constructions in mechanical engineering. Fitted with a sheet steel cage and manufactured from standard rolling-element bearing steel (100Cr6), the component primarily absorbs radial forces. Thanks to the deep raceway geometry, the design also transmits axial forces in both directions. The SKF Explorer version is characterised by a optimised internal geometry of the raceways and rolling elements.

What loads and mounting conditions characterise the 6222-2Z deep-groove ball bearing?

The bearing is primarily used in designs that accommodate shafts with a diameter of 110 mm and must withstand combined loads. With its dimensions of 110 mm inner diameter, 200 mm outer diameter and 38 mm width, the component is suitable for robust bearing arrangements. The cylindrical outer ring has no flange or groove, which means the bearing can be fitted into straight housing bores.

What is the function of the 2Z end plates and the P0 tolerance class?

The cover plates (2Z) on both sides, made of sheet steel, seal off the interior of the bearing without coming into contact with it. This prevents any additional friction during operation, which facilitates operation at higher speeds and reduces the ingress of coarse dirt particles. Manufactured to tolerance class P0 (standard tolerance or ABEC 1) and with standard radial bearing clearance, this roller bearing is designed for a temperature range of -20 to +120 degrees Celsius.
